6.	Loss Per Share

A company that has participating security holders (for example, unvested restricted stock that has nonforfeitable dividend rights) is required to utilize the two-class method for purposes of calculating earnings (loss) per share ("EPS"). The two-class method is an allocation of earnings/(loss) between the holders of common stock and a company's participating security holders. Under the two-class method, earnings/(loss) for the reporting period are allocated between common shareholders and other security holders, based on their respective rights to receive distributed earnings (i.e. dividends) and undistributed earnings (i.e. net income or loss). Currently, the Company has one class of security and has participating security holders consisting of shareholders of unvested restricted stock. The basic and diluted EPS calculations are shown below (in thousands, except per share amounts).

Basic and diluted weighted-average shares outstanding		46,719			46,617			46,717			46,615
Basic Loss Per Common Share	$	(0.60	)	$	(0.08	)	$	(1.03	)	$	(0.53	)

Dilutive Loss Per Common Share	$	(0.60	)	$	(0.08	)	$	(1.03	)	$	(0.53	)

Diluted EPS includes the dilutive effect of common stock equivalents and is computed using the weighted-average number of common stock and common stock equivalents outstanding during the reporting period. Common stock equivalents include stock options and unvested restricted stock. Diluted EPS for the three and six months ending June 30, 2011 and 2010 excluded common stock equivalents because the effect of their inclusion would be anti-dilutive, or would decrease the reported loss per share. Using the treasury stock method, the weighted-average common stock equivalents excluded from diluted EPS were 0.4 million shares during the three and six months ended June 30, 2011 and 2010.
